DEVICE FOR DISTINGUISHING DIFFERENT soRTs or COTTON DURING SPINNING OPERATIONS.

Application filed February 13, 1925, Serial No. 8,988, and in France February 14, 1924.

The present invention relates to an improvement in devices for distinguishing the different sorts of cotton during the progress of the spinning operation. Heretofore in order to distinguish the various sorts of cotton in the course of spinning, the tubes of the spinning bench-es have been marked by means of a coloured painted ring on their base, so that each sort of cotton was differentiated from the others by the colour of the tube. Generally a certain number of tubes painted with the same colour was available for each sort, and this number was suflicient as long as there was no change in the proportion of the diiierent sorts. When there was such a change, for instance if there was an unforeseen considerable larger demand for a determined sort, owing to the insutticient number or" tubes for the particular sort, it became necessary either to trans form the tubes intended for another sort by painting them over with the new colour, or to have for each sort an unnecessarily large reserve stock of tubes, or still to procure at short notice a rather important number of new tubes for which there may be no use later.

The object of the present invention is to avoid the drawbacks referred to.

IVith this object in view, the invention is characterized by the fact that the distinctive mark of the tubes is not painted thereon so that it cannot be removed, but it takes the shape of an individual marking member which is detachable and can easily be re moved, so that a tube may be readily provided with same by hand. Consequently, if an unusually large number of tubes for a determined sort of cotton is momentarily required at short notice, they may be distinguished by slipping over same the distinctive detachable marking member of the cor responding colour. By giving to the tubes a neutral colour and by having a sufiicient reserve stock of distinctive marking members for each sort of cotton, it becomes possible to satisfy the requirements for the various sorts of cotton without difficulty and without it being necessary to have a large reserve of tubes.

In order that the invention may be readily understood, an embodiment of same is, by way of example only, illustrated by the accompanying drawing, wherein:

Figures 1, 2 and 3 are respectively a vertical section, an elevation and a view from below of one type of device according to the invention, and

Figure 4 is a vertical section showing a modified type.

Referring to the drawing, A indicates the tube which has to receive the cotton. The base of the said tube A is provided with the distinctive marking member B. The latter takes the shape of a slit cuff a, made of sufiiciently elastic material such as for instance thin steel or gun-metal sheet, and painted with the distinctive colour corre sponding to the particular sort of cotton. In order to maintain the marking member a in position, it is provided at its upper portion with a band I) of smaller diameter, corresponding to the narrower portion of the tube, and adjacent the lower edge, the cuff a has formed therein a spring-like depression 0 adapted to engage in one of the notches d cut in the base of the tube. By causing the marking member to slide upwardly along. the tube, it may readily be removed, and a marking member of another colour may be slipped onto the tube in its place.

In the type illustrated by Figure 4, an inner flange 6 provided round the upper edge of the cuff a replaces the narrower portion of the embodiment illustrated by Figures 1 to 3.

I claim:

1. A slit marking cuff of thin metal adapted to surround removably the enlarged base of spinning-tubes, having at its upper edge an inner flange and a narrower neck engaging the tube, and a spring-like depression adjacent its lower edge, capable of engaging one of a series of notches cut at intervals in the periphery of said base.

2. A slit marking cuff of thin metal adapted to surround removably the enlarged base of spinning-tubes, having at its upper edge an inner flange engaging the shoulder of the base, and a spring-like depression adjacent its lower edge, capable of engaging one of a series of notches cut out at intervals in the periphery of said base.

In testimony whereof I have signed hereunto my name. i
